Description
Introduction
The ABB TR/A1.1 Time Receiver GPS (Product ID: 2CDG120060R0011) is a surface-mounted KNX system component designed to receive and process GPS satellite signals, while integrated sensors measure ambient brightness and outside temperature. Equipping KNX (TP) bus systems with highly reliable synchronization, the TR/A 1.1 transmits precise system time, calendar date, geographical coordinates, sunrise, and sunset times directly onto the bus network. This device is part of our KNX system devices range.

Featuring an IP54 degree of protection and an integrated bus coupler, the TR/A 1.1 functions without requiring batteries or manual operation. It provides 1 channel with a weekly program option, making it an essential device for building automation installations where automated time synchronization and outdoor environmental sensing are required.
